Fixed Inductors

Inductors are electronic components that store energy in a magnetic field when an electric current is applied to them. In the simplest form, they comprise a coil of wire wrapped around a ferromagnetic core and are used extensively in radio frequency circuits, including those used in mobile phones and wireless internet. The DRA127-470-R is one type of fixed inductor, characterized by its fixed inductance of 47 µH, a current rating of 4A and an operating temperature range of – 40ºC to 85ºC.

Applications of the DRA127-470-R

The DRA127-470-R is suitable for a broad range of electronic applications that require a high-performance inductor. These include switching-mode power supplies, switching technology, DC-to-DC converters, battery-powered circuits and filtering circuits. It is also used in radio frequency circuits and telecommunications systems.

Working Principle

The DRA127-470-R functions by storing energy in a magnetic field when an electric current is passed through it. This is achieved through the use of a coil of wire that is wrapped around a ferromagnetic core. When a current is applied, the magnetic field is produced around the coil, and this field then interacts with the electric current, which in turn creates an electromagnetic field. The strength of the magnetic field increases with the amount of current that is passed through the inductor.The amount of energy stored in the inductor\'s magnetic field is determined by the inductance of the coil. The inductance is defined as the ratio of the magnitude of the induced voltage to the rate of change of the current flowing through the inductor. The DRA127-470-R has a fixed inductance of 47 µH, which implies that it will always store the same amount of energy, irrespective of any changes in the current flowing through it.The energy stored in the magnetic field can be used to power circuits. When the inductor is connected in series with a circuit, the current traveling through it is resisted by the magnetic field and the energy stored in it is released. The amount of voltage and current released is determined by the inductance of the coil and the amount of current flowing through it.

Conclusion

The DRA127-470-R is a fixed inductor that is suitable for a broad range of electronic applications. It derives its fixed inductance of 47 µH from the coil of wire that is wrapped around a ferromagnetic core. When a current is applied, the magnetic field interacts with the electric current, creating an electromagnetic field which stores energy. When the inductor is connected in series with a circuit, the energy stored in the magnetic field is released, powering the circuit.
